Abstract

Systems and methods are provided for reversibly controlling a size and/or restricting the movement of a body orifice, such as a pyloric opening, using an implantable device configured to allow a distance between opposed ends thereof to be adjusted. A device is provided having attachment members and a connector portion extending therebetween and configured such that a size of the pyloric opening is decreased upon the implantation of the device. The connector can be adjustable to allow a size of the pyloric opening to be adjusted after it has been restricted. The connector can include two or more bridge portions having different lengths such that cutting a first bridge portion can increase the distance between the attachment members so as to increase the size of the pyloric opening. To revert to a natural size of the body orifice, the entire connector can be cut or otherwise broken and/or removed.

In implant 202 after implantation site is inserted into tissue, portions of proximal 214a and distal part 214b can be extended to form the nearside alar part 314a shown in Fig. 3 and distally alar part 314b.In embodiment shown in Fig. 2 to Fig. 6, slit 216a, 216b are configurable to portions of proximal 214a and distal part 214b and are respectively formed two groups of alar parts.In one embodiment, portions of proximal 214a and distal part 214b is respectively formed two groups of eight alar parts.It should be apparent that, may be structured to form any amount of alar part according to the portions of proximal of the implant of some embodiments and distal part, these alar parts can be aligned with each other or be radially staggered, because described embodiment is not limited in this respect.
Fig. 3 illustrates, in deployed configuration, the portions of proximal 214a of implant 202 extends and forms nearside alar part 314a, and distal part 214b extends and forms distally alar part 314b.Alar part 314a, 314b are formed by the material between slit 216a, 216b, and along with outer slender bodies 212 rotates and/or compresses, this material outwards deforms.Alar part 314a, 314b can concurrently form or successively be formed, for instance by launching distally alar part 314b before nearside alar part 314a.But in certain embodiments, nearside alar part 314a can be previously formed being formed distally alar part 314b.
Alar part 314a, 314b in implant 202 can be formed by rotating and/or compress this device 202.Although various technology can be used for launching and activating this device 202, in certain embodiments, implant 202 is removably attached to operating mechanism, and operating mechanism is suitable to implant 202 introduces health and is suitable to apply axial force and revolving force to slender tube body 212 so that the local of slender tube body 212 stretches out.Fig. 2 illustrates that guiding piece 204 is connectable to the bar 209 of operating mechanism (not shown).In one embodiment, nearside alar part 314a and distally alar part 314b can include being formed along with alar part and grasping the tissue engaging mechanisms of tissue.Alar part 314a, 314b can by such as compressing portions of proximal 214a and distal part 214b along with portions of proximal 214a and distal part 214b rotates formed to form alar part.
Body 212 can be made up of the various materials including absorbable material and nonabsorable material.In one embodiment, implant 202 is made (i.e. the insignificant deformation of elastic part) by the deformable material standing plastic deformation.As non-limitative example, exemplary material include any can re-absorption (such as biocompatibility and/or Bioabsorbable) material, for instance comprise titanium (and titanium alloy), magnesium alloy, rustless steel, polymeric material (artificial and/or natural), shape-memory material asPottery etc..By adding X-ray visible material such as ferric oxide particles, rustless steel, titanium, tantalum, platinum or other suitable equivalent any, usual radiopaque material such as magnesium alloy can be enhanced and to become X-ray visible.In certain embodiments, also alternately or alternatively it is used to form including other material of non-permeable material such as polyethylene terephthalate and polyvinylidene chloride and semipermeable materials such as polylactic acid and/or is coated with body 212.
In using, as in figure 2 it is shown, there is the device 100 being attached to the implant 202 being in pre-deployment configuration thereon endoscope or laparoscopically mode can be inserted into patient body.The delivery system (Fig. 2) such as in the proximal end of bar 209 with guiding piece 204 can be used to the device 100 engaged with implant 202 is sent into implantation site.It is to be understood that device 100 and implant 202 can be delivered to implantation site in any way as suitable.Device 100 can be engaged to implant 202, or alternatively, in some instances, device 100 and implant 202 can be delivered to implantation site respectively.
Although not being illustrated in figs. 2-6, but in certain embodiments, can be used for this device of more than one is anchored to tissue for the first deployable implant or main deployable implant that device such as device 100 is anchored to tissue.Such as first deployable implant 202 may pass through the attachment of the more than one of this device such as the ring of the ring 102 that is similar in Fig. 2 or other type of (multiple) attachment, thus makes the device including these attachments connect with implant 202.In the embodiment shown in Figure 2, the ring of more than one can be placed in above the near-end 205a of body 212 to recline ring 208.So, when the first implant 202 is unfolded, the device of more than one (as two, three or more) be anchored to tissue.Each device that identical main implant is anchored is used to can be used for restriction pyloric ostium size.Such as, described device can position in the way of extending across pyloric ostium at least partly, and each device can use respective second implant or secondary implant to be fixed on each different positions near pyloric ostium.Secondary implant can be fixed to tissue at the opposite side of the position of fixing main implant.Use the first identical implant the device of more than one is anchored to tissue method embodiment as shown in figure 13.
As it has been described above, described technology is particularly well-suited to control pylorus size.Thus, in certain embodiments, implant 202 and device 100 can be delivered to pyloric ostium.Once implant 202 is sent near pyloric ostium, the tip of implant 202 just can be used in pylorus side piercing tissue.Opening in being consequently formed tissue and after desired locations positioning implants 202, implant 202 can be manipulated by so that the portions of proximal 214a and distal part 214b of body 212 extend, thus launching nearside alar part 314a and distally alar part 314b to engage tissue therebetween.In the fig. 3 embodiment, portions of proximal 214a is configured to define the two groups of alar parts being radially staggered toward each other.Similarly, distal part 214b is configured to define the two groups of alar parts being radially staggered toward each other mutually.Nearside alar part 314a and distally alar part 314b can be in alignment with each other, as shown in Figure 3.
In certain embodiments, alar part 314b in distally can be unfolded before nearside alar part 314a launches.Formed in the tissue wall side of pyloric ostium and puncture and after implant 202 is positioned so that the opposite sides that middle part 218 is placed in tissue wall through points of puncture and portions of proximal 214a and distal part 214b, implant 202 can be manipulated by so that distal part 214b launch and at formation distally, tissue wall side alar part 314b.Distally alar part 314b extend after, implant 202 can be manipulated by so that portions of proximal 214a extension and tissue wall opposite side formed nearside alar part 314a.But in certain embodiments, nearside alar part 314a can be unfolded before distally alar part 314b launches.Addedly or alternatively, nearside alar part 314a and distally alar part 314b can concurrently form or concurrently form at least partly, thus at least some of and formation nearside alar part 314a the period forming the period of distally alar part 314b overlap.
No matter nearside alar part 314a and distally alar part 314b is formed in which way and alar part expansion order, owing to alar part is formed, therefore device 100 is anchored to tissue at body orifice such as pyloric ostium place by implant 202.Implant 202 and can be applicable to other implanting device of described technology can in the tissue near implanted pylorus and/or in implanted gastric tissue.
After implant 202 is sufficiently spread out, the operating mechanism (not shown) being connected to guiding piece 204 at nearside can separate with implant 202 and be removed from implantation site, as shown in Figure 3.As a result, implant 202 remains fixed in tissue, engages with device 100 simultaneously.
Reviewing Fig. 2, in the unexpanded configuration of implant 202, most advanced and sophisticated 220 can highlight from the distally of targeting part 210.In certain embodiments, after implant 202 is inserted implantation site, or extending at portions of proximal 214a and distal part 214b and form nearside alar part 314a and distally alar part 314b with before or after engaging tissue therebetween, the basis of most advanced and sophisticated 220 implants 202 being retractable into expansion is internal.Fig. 4 illustrates that most advanced and sophisticated 220 are retracted into the intrinsic implant 202 of implant.So, most advanced and sophisticated 220 ends can be eliminated in the histoclastic probability of implantation site.
Fig. 4 illustrates that its nearside alar part 314a and distally alar part 314b is fully deployed and is attached to the implant 202 of device 100 by attachment 102.In implant 202 after pyloric ostium side is fixed to tissue, another implant i.e. the second implant 402 being in unexpanded configuration also such as can be attached to device 100 by the second attachment 104, as shown in Figure 4.Second attachment 104 can be constituted in the form of a ring, is similar to the first attachment 102, but may be used without other configuration.As shown in Figure 4, the second implant 402 can be similar to the first implant 202 and can with its distal tip 420 through the second attachment 104.
Similar to the first implant 202, the second implant 402 can have slender tube body 412, and this body includes near-end 405a and far-end 405b.As it is shown in figure 5, slender tube body 412 can include the portions of proximal 414a and distal part 414b and the middle part 418 that are respectively provided with nearside slit 416a and distal slit 416b.Distally conical guide portion 410 can extend from the far-end 405b of body 412, and distal tip 420 can be distally extending from targeting part 410.Ring 408 can be located at the near-end 405a place of body 412 and prevents attachment 104 proximad from skidding off implant 402 as backstop.Can being the guiding piece 404 of a part for means of delivery assembly the near-end 406a that is connectable to the second implant 402, means of delivery assembly be configured to implant 402 is delivered to surgical sites.Portions of proximal 414a and distal part 414b may be structured to extension and forms respective nearside alar part and the distally alar part that joint is organized therebetween.
In using, after implant 402 is held by the attachment 104 of device 100, (or size to be controlled other body orifice) the size reduction that device 100 can be applied pulling force so that pyloric ostium.Operating mechanism or be attached to any other appropriate device (Fig. 4) of the detachably connectable guiding piece 404 in device 402 near-end 406a and can be used in the implant 402 that moves up along the side of pyloric ostium diameter, thus the device 100 engaged with implant 402 is pulled over opening to reduce its size.In other words, the second implant 402 make the second implant 402 move apart the first implant 202, thus can be anchored in tissue in the side contrary with the first implant 202 of pylorus.One or more components (such as connector 106 and/or other component) of device 100 can be made up of elastomeric material, thus can be stretched when it is pulled contraction opening timer 100.
After arriving the desired locations of device 100, when device 100 is tightened up, implant 402 can be used to the opposite side piercing tissue relative with the side that implant 202 has been launched at pyloric ostium.Subsequently, implant 402 can be unfolded, thus portions of proximal 414a and distal part 414b extension forms nearside alar part 514a as shown in Figure 5 and distally alar part 514b, this can launch similarly to complete with alar part 314a, 314b.When the suitable gripping device that device 100 is connected to implant 402 is handled, device 100 can be moved, thus around pylorus hole and/or tissue near pylorus hole is folded or gauffer, or be otherwise manipulated to reduce pyloric ostium size.
After implant 402 is fully deployed, the operating mechanism (not shown) and the guiding piece 404 that are connected to guiding piece 404 near-end can separate with implant 402 and be removed from surgical sites, as shown in Figure 5.Although it should be noted that Fig. 5 illustrates distal tip 220,420, but most advanced and sophisticated 220,420 after it is used to pierce tissue regracting (as in the diagram for shown in implant 202), to avoid being likely to the prominent sharp edges that damage is organized.This is useful especially for reducing sensitive organization's wound in gastrointestinal tract.
Owing to the second implant 402 is unfolded after the first implant 202 is launched, therefore device 100 will be positioned in pyloric ostium place, thus connector 106 extends across pyloric ostium and between the first implant 202 and the second implant 402.Thus, device 100 is fixed in tissue by implant 202,402 in the corresponding opposite sides of opening.So, the natural size in pylorus hole is reversibly reduced and can be kept the desired size of opening by the connector 106 of this device 100.Pyloric ostium can keep any persistent period in part opens state, may return to complete opening-wide state when needed.
It should be understood that deployable implant 202,402 is not necessarily in the implanted tissue of corresponding opposite sides of pyloric ostium.For controlling pyloric ostium size, deployable implant 202,402 (or being other deployable implant any of same purpose) can any suitable relevant position near pyloric ostium implanted.
Fig. 6 be shown in the nearside alar part 314a and distally alar part 314b of the first implant 202 at least one be unfolded and the rearview of device 100 when at least one in the nearside alar part 514a and distally alar part 514b of the second implant 402 is unfolded.When the portions of proximal 214a radial expansion of the first implant 202 forms nearside alar part 314a, nearside alar part 314a can be directed at distally alar part 314b to help to be attached to tissue.Equally, the nearside alar part 514a of the second implant 402 can be directed at distally alar part 514b, as shown in the example of Figure 6.It is to be understood that the nearside alar part of implant and distally alar part can be radially staggered toward each other.
Although further, it should be understood that Fig. 4-6 illustrates that essentially identical implant 202,402 will be connected to device 100, but implant 202,402 can be various configuration.Can addedly or alternatively use and be configured to be held and in implanted tissue with any kind of extendable device that holding means 100 is in place by the attachment of device 100, because embodiment is not limited in this respect.Implant 202,402 may be structured to form any appropriate number of alar part, and the alar part quantity between implant can be identical or different, and nearside alar part and distally alar part can align each other or stagger.Additionally, only citing illustrates that first attachment 102 holds implant 202, because attachment 104 or main implant can be used as so that device 100 is anchored to tissue.
After implant 202,402 is launched, device 100 can pass through to be connected to implant 202,402 by attachment 102,104 and be maintained at surgical sites place, as shown in Figure 5.Implant 202,402 can be unfolded connecing juxtapyloric diverse location in tissue, thus the connector 106 of device 100 is at least partially across limited aperture.Therefore connector 106 will set orifice diameter.But in some instances, being arranged to the mode in health according to device 100, connector 106 can position in the way of not passing through aperture.
As it has been described above, the part 108,110,112 of connector 106 is configurable to the length of the Part III 112 grown most less than port size (such as diameter or other size), this port size can be controlled by device 100.Should be appreciated that, only citing illustrates three parts 108,110,112, because connector 106 can include any appropriate number of different length part (such as two, four, five etc.), it can be used to reduce and sequentially subsequently (or otherwise) increases body orifice size.If being no longer desire to restriction body orifice size (as when loss of weight is expected in Bariatric success and realization or in what its situation in office), the any remaining part not yet cut off of all parts 108,110,112 or connector 106 can be cut off or otherwise disrumpent feelings, make aperture recover to its natural size, aperture is not imposed any restriction.
Fig. 7 and Fig. 8 illustrates another embodiment that can be used to control the device 700 of the size of body orifice such as pyloric ostium.Device 700 is configurable to be combined with the first implant and the second implant, and the first implant and the second implant can be similar to above-mentioned first implant the 202, second implant 402 in certain embodiments.Fig. 8 illustrates the first deployable implant 802 can being combined with device 700.Device 700 can be configured to be arranged on the means of delivery assembly including the first implant 802 and surround this means of delivery assembly.
As shown in Figure 7 and Figure 8, device 700 generally includes the elongated ridges 702 with near-end 702a and far-end 702b.At least one attachment is formed on ridge 702 or is connected with this ridge so that device and implant connect.In the embodiment shown, far-end 702b forms the first attachment 701 being configured to directly be combined with the first implant, and device 700 includes the second attachment 709 for being combined with the second implant.First attachment 701 and the second attachment 709 limit the connector part 704 that extends betwixt for remaining attached to the distance between the first implant and second implant of attachment 701,709.Connector part 704 can include bridge part for allowing the spacing of implant is adjusted.This device may also comprise the 3rd attachment 711, and it is shown disposed on the near-end 702a of ridge 702 for being connected to the 3rd implant, as will be described in detail.
Attachment 701,709,711 can have various configuration.In the embodiment shown, the first attachment 701 is only the distalmost end 702b of ridge 702, and it is configurable to directly be combined with implant, as used bonding agent or other attachment technology known in the art.But selectively, attachment 701 can be that ring or other component form connect and integrated implant.Second attachment 709 and the 3rd attachment 711 also can have various configuration, but are illustrated as removable and that slidably receive corresponding deployable implant ring or circle.Second attachment 709 and the 3rd attachment 711 are also configurable to hold the means of delivery through it, as shown in Figure 8, deliver the implant equipped with device 700 to allow means of delivery to be used for.Ring can be made up of various materials and can have various degrees of pliability/rigidity and/or elasticity.It should be understood that attachment can have other configuration any.
Connector part 704 also can have various configuration.In the embodiment shown, connector part 704 has between attachment 701,709 and has multiple brackets of different length.Especially connector part 704 includes the short bracket 706 along ridge 702 formation and elongate bracket 707.But this device can include any amount of bracket.Bracket is preferably arranged for and mutually strides across, and each bracket has the size of increase relative to the bracket being arranged there between.Each bracket especially can have generally U-shaped configuration, and U-shaped configuration has the opposite end being connected to ridge 702.As it can be seen, short bracket 706 includes the first end 706a and the second end 706b that are connected to ridge 702, elongate bracket 707 similarly includes the first end 707a and the second end 707b that are connected to ridge 702.The first end 706a and the second end 706b of short bracket 706 corresponding position between the first end 707a and the second end 707b of elongate bracket 707 is connected to described ridge.As a result, bracket 706,707 is connected to ridge 707 and forms three bridge parts of connector 704.First bridge part 705 of ridge 702 is particularly formed between the first end 706a of short bracket 706 and the second end 706b, and the first bridge part 705 has the first length.Short bracket 706 limits second bridge part with the second length, and the second length is equal to the second bridge part length measured along the bridge part between end 706a, 706b.Elongate bracket 707 limits the 3rd bridge part with the 3rd length, and the 3rd length is equal to the 3rd bridge part length measured along the bridge part between end 707a, 707b.Therefore the first bridge part 705 is the shortest, and the second bridge part (i.e. bracket 706) is longer than the first bridge part 705, and the 3rd bridge part (i.e. bracket 707) is the longest in these parts.
Bracket 706,707 can be integrally formed with ridge 702, or they can be attached to ridge 702 in any way as suitable.Bracket 706,707 can extend from ridge 702 along reciprocal both direction as shown in the figure, or they can be all located at the same side of ridge.In the embodiment shown, bracket 706,707 is respectively provided with U-shaped or semi-circular configuration.It will be apparent, however, to one skilled in the art, that bracket 706,707 can have any size and/or shape to form the bridge part with different length of connector 704.Additionally, device 700 can comprise more than the bracket of two and/or has the component of other size and dimension any that can form any appropriate number of bridge part.
As it has been described above, device 700 can include the 3rd attachment 711 being positioned at the most proximal end 702a of ridge 702.In certain embodiments, not using the second attachment 709, the 3rd attachment 711 is alternatively used for being combined with the second deployable implant.In such an embodiment, device 700 can be considered as the connector part 704a having and extending to the 3rd attachment 711 from the first attachment 701.Therefore, the 3rd attachment 711 can be combined with the second deployable implant, for instance when expectation reduce larger open (or major part of opening) even if size so that opening size reduces but when connector 704 length is still not enough to stride across opening.Alternatively, when utilizing connector 704a that opening is restricted to smaller extent compared with the situation utilizing connector 704 to make the opposite sides of opening draw closer together, the 3rd connector 711 can be used.Although Fig. 7 and Fig. 8 is not shown, but device 700 can only include an attachment (such as 709 or 711) or include the attachment more than two, and different attachments can be used for mating with the second implant under various circumstances.
Should be understood that device 700 can have appropriate number of any feature that is that be connected to ridge 702 and that have any suitable configuration and size.Such as a modification, device 700 can only include one of bracket 706,707.As another modification, device 700 can include one or more brackets with closed circle cross section, and closed circle cross section can have the cut portion of any suitable shape.The size of feature, configuration and quantity may be selected to and can control pyloric ostium increasing size according to patient profiles, loss of weight progress and any other factors.
In using, the connector part 704 of device 700 can be shaped as the effect of the bridgeware making attachment 701,709 maintenance predetermined distance.Connector 704 includes three bridge parts as shown in the figure, namely the first bridge part 705, be also referred to as the short bracket 706 of the second bridge part 706 and be also referred to as the elongate bracket 707 of the 3rd bridge part 707 hereinafter hereinafter.When device 700 implanted with limit pyloric ostium size and first bridge part the 705, second bridge part 706 and the 3rd bridge part 707 complete time, initial first distance between the attachment 701,709 mate with the first implant and the second implant respectively will depend upon which (as equal to) the shortest first bridge part 705 length.
Be it desired to increase subsequently port size, then one or more in bracket can sequentially or simultaneously be cut off, disrumpent feelings or otherwise change and make the spacing of attachment 701,709 change.Such as the first bridge part 705 can be cut off the first end 706a and the second end 706b to decontrol short bracket 706 along its length at an arbitrary position, it is allowed to end 706a, 706b divide out.As a result, the spacing of attachment 701,709 is by mobile to the longer second distance such as determined by the second bridge part 706 from the first distance such as kept by the first bridge part 705.Be it desired to increase pyloric ostium size further, then short bracket 706 also can be cut off the first end 707a and the second end 707b to decontrol elongate bracket 707 along its length at an arbitrary position, it is allowed to end 707a, 707b are spaced further apart.As a result, the spacing of attachment 701,709 will move to longer 3rd distance such as determined by the 3rd bridge part 707 from the second distance such as determined by the second bridge part 706.It is undesirable that reduce pylorus port size, big bracket 707 also can be cut off, thus device 700 no longer makes implant keep at a distance from each other, therefore pyloric ostium becomes opening wide completely.(multiple) cut-off parts can optionally be removed from implantation site subsequently.
As it has been described above, device 700 can be used in conjunction with the means of delivery assembly being used for delivering implant.Fig. 8 illustrates the first implant 802 that delivery components can be used to be delivered to implantation site, and delivery components includes elongated tubular guiding piece or the bar 804 with the first implant 802 being removably attachable to its far-end.In certain embodiments, device 700 is configurable to the size and dimension of its applicable elongated tubular guiding piece 804.Therefore as shown in Figure 8, the attachment 709,711 of device 700 is configurable to accommodation guiding piece 804 wherein, and this allows implant 802 to be passed through Wicresoft's mouth and be not subject to the interference of device 700.
As it has been described above, the first implant 802 can be passed through to combine be connected to device 700 at far-end 702b and first attachment 701 of device 700.First implant 802 is configurable to similar to above-mentioned first implant 202 and the second implant 402 and can have the slender tube body including portions of proximal 814a, distal part 814b and middle part 818.Portions of proximal 814a and distal part 814b is configurable to extension and forms corresponding nearside alar part and distally alar part (not shown), nearside alar part and distally alar part joint tissue therebetween, as mentioned above.Distally conical guide portion 810 extends from body distal end, and distal tip 820 is distally extending from targeting part 810.As shown in Figure 8, ring 808 may be provided at body near-end and can have the first attachment 701 of combination fixed thereto.Attachment 701 at the far-end 702b place of device 700 can bonding, weld or be otherwise attached to the first implant 802.It should be understood that the first implant 802 can be combined with device 700 in any other suitable way, including using different types of attachment.
In using, the first implant 802 is delivered to implantation site together with device 700 in unexpanded configuration.In order to the first implant 802 being delivered to implantation site as being sent into pyloric tissue, distal tip 820 can be used in this site piercing tissue.After the first implant 802 is properly positioned at implantation site, being included in means of delivery assembly can be maybe that the operating mechanism of independent suitable instrument can be used for operation the first implant 802 so that portions of proximal 814a and distal part 814b expansion and form nearside alar part and distally alar part.With above in relation to after being similarly constructed alar part described in implant 202,402, guiding piece or bar 804 can separate with the first implant 802, thus the first implant 802 is discharged from delivery components.In the example shown, bar 804 can skid off attachment 709,711.
After the first implant 802 is unfolded, the second implant (not shown) may pass through the attachment 709,711 of device 700 in the lump for device 700 being positioned at appropriate location to control body orifice size.Second implant can to arbitrary implant 202,402 and 802 similar, or it can be configured for the different device being fixed in tissue.In certain embodiments, the second implant can be passed through the second attachment 709 and be inserted into, and after implant is extended in body orifice surrounding tissue, it can remain engaged with this implant.But or make the second implant through the 3rd attachment 711 or form other structure any on device 700.Such as in certain embodiments, the attachment more than two being connected to ridge 702 can be formed at the nearside of bracket 706,707.
As it has been described above, different attachments is optionally used for being combined device 700 with the second implant, according to device 700 relative to the position of pyloric ostium, desired pyloric ostium limited degree, pylorus hole dimension and/or any other factors.Such as, if device 700 positions to cross over pyloric ostium diameter (or widest portion) mode, then the second implant can be through the 3rd attachment 711, and the 3rd attachment is located most distal from the first attachment 701 being combined with the first implant 802.Or, if device 700 is implanted in the way of it misplaces relative to pyloric ostium diameter (or widest portion), then available the second attachment 709 closer to the first implant 802 of the second implant is combined with device 700.Therefore, multiple features of device 700 allow the flexible positioning of device 700 and can allow pyloric ostium constriction in various degree.
When the first implant 802 (Fig. 8) with when being all fully expanded in this unshowned second implant, a part for device 700 can be used to control pyloric ostium size such as the connector part 704 extended between the attachment 701,709 being combined with the first implant and the second implant respectively.In some above-mentioned embodiments, after pyloric ostium has utilized intact device 700 tentatively to be limited, the bridge part 705,706,707 of connector 704 can be cut off, disrumpent feelings, remove or otherwise change and increase pyloric ostium size.This can complete when being implanted at first in implant and device, or now regulate at least one follow-up work process of pylorus size in hope and complete.
Device 700 is made by can bear material that is that stomach shrinks and that can be adjusted to control pylorus bore dia when food is forced into small intestinal.Exemplary materials can include and the above-mentioned material identical for the material manufacturing this device 100 or other material any.
Fig. 9 illustrates another embodiment that can be used for controlling the device 900 of the size of body orifice such as pyloric ostium.Similar to the device 700 of Fig. 7 and Fig. 8, device 900 may be structured to adapt to the size and dimension of the delivery components for the first deployable implant is delivered to tissue.Device 900 may be mounted to that on delivery components (not shown) and available first deployable implant is anchored in tissue.
As it is shown in figure 9, device 900 can include the first attachment 901 and the second attachment 909, the ridge 902 that extends between the first attachment 901 and the second attachment 909 and the bracket 906 with the first end 906a and the second end 906b that are connected to ridge 902.In the embodiment shown, bracket 906 semicircular in shape or U-shaped, but it can be other shape any.By non-limiting example, attachment 901,909 is configurable to ring-type and can be positioned on the opposite sides of bracket 906.As it is shown in figure 9, bracket 906 is placed in the center of ridge 902, the first attachment 901 is positioned at the distalmost end 902b place of the ridge 902 of device, and the second attachment 909 is positioned at the most proximal end 902a place of device 900.
In the embodiment shown, the ridge 902 of device 900 can form the connector 904 of the spacing for controlling attachment 901,909 be fixed to the tissue near pyloric ostium at this device after.This connector plays the function similar to above with respect to the connector described in Fig. 7 and Fig. 8, but only includes single bracket 906.A part for the ridge 902 particularly extended between the first end 906a and the second end 906b of bracket 906 can form the first bridge part 905, and it keeps the first attachment 901 and the second attachment 909 first distance.When the first bridge part 905 is cut off, the first end 906a and the second end 906b of bracket 906 is removable separately, and bracket 906 can limit the second bridge part keeping the first attachment 901 and the second attachment 909 second distance, and second distance is more than the first distance.
In using, first attachment 901 and the second attachment 911 all can combine with corresponding deployable implant (such as above-mentioned any implant 202,402,802), thus when implant is launched, device 900 is anchored to tissue near body orifice such as pyloric ostium.Device 900 can be positioned on pyloric ostium place, thus connector 904 positions at least partially across opening.It will be understood to those of skill in the art that the orientation of device 900 can be contrary, thus the distalmost end 902b of device 900 becomes most proximal end 902a, because above-described embodiment is not limited to device 900 and can be anchored to specific orientation and the position of tissue.
Launching in deployable implant and device 900 with after being fixed to tissue at pyloric ostium place, the spacing of attachment 901,909 can tentatively depend on the length of the ridge 902 extended between attachment 901,909.The connector 904 of device 900 can be subsequently used to regulate pylorus port size.Such as after tentatively limiting pyloric ostium size by intact device 900, the need to, first bridge part 905 can be cut off to increase opening size, thus the spacing of attachment 901,909 increases and becomes dependent on the length of the second bridge part being equivalent to bracket 906.If needing to increase further opening size, it is possible to expand by cutting off bracket 906, thus opening size becomes unrestricted.
It will be understood to those of skill in the art that, device 900 can comprise more than the bracket (such as two, three, four or more) of, thus device 900 can be cut off once, twice or more than twice, regulate body orifice size so in multiple steps.Such as similar to device 700 (Fig. 7), device 900 can include more than one bracket, and it has any longitudinal length and positions in any way along ridge 902.Additionally, device 900 can include any further feature of any size and configuration, it contributes to device 900 being delivered to implantation site and allowing to use in different patients with for different conditions.
Figure 10 illustrates another embodiment that can be used for controlling the device 1000 of body orifice such as pyloric ostium size.Similar to device 700 (Fig. 7 and Fig. 8) and device 900 (Fig. 9), device 1000 is configured to adapt to the size and dimension of the delivery components for the first deployable implant is delivered to implantation site.In order to device 1000 is delivered to implantation site, it can be combined and be installed in the first implant in the delivery components being connected to the first implant near-end.
As shown in Figure 10, device 1000 can include the first attachment 1001 and the second attachment 1009 and the connector 1004 extended between the first attachment 1001 and the second attachment 1009.Connector 1004 can include straight ridge 1003 and be connected to first alar part 1005, second alar part 1007 of arch of ridge 1003, flap portion 1011 and the 4th alar part 1013.As shown in Figure 10, the first alar part 1005 has the first end 1005a being connected to the first attachment 1001 and the second end (not shown) being connected to ridge 1003.Second alar part 1007 has the position identical in the position being attached to ridge 1003 with the second end of the first alar part 1007 but is attached to the first end (not shown) of ridge 1003 at the opposite side of ridge 1003.Second alar part 1007 has at the second end 1007b being attached to ridge 1003 from first end a distance.Flap portion 1011 has the position identical in the position being attached to ridge 1003 with the second end 1007b of the second alar part 1007 but is attached to the first end 1011a of ridge 1003 at the opposite side of ridge 1003.Flap portion 1011 has at the second end 1011b being attached to ridge 1003 from first end 1011a a distance.4th alar part 1013 has the position identical in the position being attached to ridge 1003 with the 3rd end 1011b of flap portion 1011 but is attached to the first end 1013a of ridge 1003 at the opposite side of ridge 1003.4th alar part 1013 has the second end 1013b being attached to the second attachment 1009.Thus, in this embodiment, attachment 1001,1009 is not directly connected to ridge 1003.
The attachment 1001,1009 constituted in the form of a ring all can combine (as passed through to hold implant wherein) with corresponding deployable implant, thus when implant is launched, device 1000 is anchored to tissue near body orifice such as pyloric ostium.Such as the first attachment 1001 can combine with the first implant (such as Fig. 8 shown in but unshowned first implant 802 of Figure 10), and the second attachment 1009 can be combined with the second implant.Device 1000 can so be implanted, i.e. after device 1000 is fixed to pyloric ostium tissue around, and connector 1004 can extend across pyloric ostium at least partly and can be used for regulating the spacing of attachment 1001,1009.
Device 1000 implanted and after limiting pyloric ostium (or body orifice) size, it is it desired to increase subsequently opening size, then ridge 1003 Part I 1018 or Part II 1020 can be cut off or otherwise disrumpent feelings (and/or removing), thus the distance increased between the attachment 1001,1009 being combined with deployable implant.In the embodiment shown, if the Part I of ridge 1,003 1018 is cut off, then the first end of the second alar part 1007 and the second end (only illustrating the second end 1007b) will be allowed to separately, thus increase the spacing of the first attachment 1001 and the second attachment 1009.If the Part II of ridge 1,003 1020 is cut off, then the first end 1011a and the second end 1011b of flap portion 1011 will be allowed to separately, thus increase the spacing of the first attachment 1001 and the second attachment 1009.As all cut-off in fruit part 1018,1020, then attachment 1001,1009 will be moved apart further.
If without limiting body orifice size, then the first alar part 1001 or the 4th alar part 1013 can be cut off so that attachment 1001,1009 is completely separate from each other.It is understood that ridge 1003 can be cut off the spacing to regulate attachment 1001,1009 in the arbitrfary point between tab end.Such as in some instances, the part 1018 of the second alar part 1007 and ridge 1003 all can be cut off so that attachment 1001,1009 is completely separate from each other, in other example, the part 1020 of alar part 1011 and ridge 1003 all can be cut off so that attachment 1001,1009 is separated from each other.It should be understood that be that the point that can be cut off of device 1000 is simply illustrated.
It will be understood to those of skill in the art that device 1000 can include any number of alar part (such as three, five or more) so that device 1000 can be cut off once, two or more times, thus regulate body orifice size in multiple steps.Additionally, device 1000 can include any further feature, such as arbitrary characteristics and other suitable feature of device 700,800.
Figure 11 A-11C schematically shows an embodiment of the method using the device described herein such as device shown in Figure 1A-1C and Fig. 2-6.Figure 11 A is the illustrative examples of the pylorus 1100 with pyloric ostium or opening 1102, and this pyloric ostium or opening are not restricted, thus pyloric ostium 1102 has its natural size.Pyloric ostium is the sphincter with ring or smooth muscle or the formation of valve form, it should be understood that Figure 11 A-11C diagrammatically illustrates pyloric ostium 1102 very much.
Figure 11 B illustrate device 100 can near pyloric ostium 1102 implanted and can be used for control pyloric ostium size.As shown in Figure 11 B, the first deployable implant can be unfolded in tissue in the first each relative side 1104 of pyloric ostium 1102 and the second side 1106 with the second implant 402 with the second deployable implant such as the first implant 202.As mentioned above, device 100 can first pass through expansion the first deployable implant and be anchored in tissue (the first side 1104 as at pyloric ostium 1102), first deployable implant is combined with the attachment of this device, as the first deployable implant 202 is combined with attachment 102.
At device 100 after the first side 1104 is anchored tissue, device 100 is tightened up and is positioned in the way of connector 106 extends across pyloric ostium 1102, as shown in Figure 11 B.Subsequently, the second implant 402 is unfolded and is fixed on the second relative side 1106 of pyloric ostium 1102.So, device 100 is positioned to regulate the size of pyloric ostium 1102.It should be understood that device 100 can first be anchored in tissue in the second side 1106, it is fixed to tissue in the first side 1104 subsequently.Should also be appreciated that, implant 202,402 can be fixed to any position near pyloric ostium 1102, because above-mentioned technology is not limited to any ad-hoc location that implant 202,402 (or other implant any that in addition use or replacement use) can be fixed in tissue.
Figure 11 B and Figure 11 C illustrates the rearview of the first implant 202 and the second implant 402, and it is similar to the view of the implant 202,402 shown in Fig. 6.Therefore, the attachment 102,104 being combined with the first implant 202 and the second implant 402 respectively of the not shown device 100 of Figure 11 B and Figure 11 C, and the first implant 202 and the second implant 402 be shown in deployed configuration.
As shown in Figure 1B illustrates, the spacing of attachment 102,104 can control by cutting off the part 108,110,112 with different length of connector 106.Thus as shown in Figure 1A (its not shown deployable implant), after implant 202,402 is launched, the initial distance between attachment 102,104 can be the first distance d as set by the length of the Part I 108 of connector 1061, Part I is its shortest part.
Figure 11 B illustrates that the size of pyloric ostium 1102 can be passed through to set the first distance d between implant 202,4021Being limited at first, it can be same or about with the spacing of attachment 102,104.Also as shown in Figure 1A, the first distance d1Set by the Part I 108 of connector 106.Therefore, the length of the shortest part of the connector 106 of device 100 can be used to define the initial desired distance between the first attachment 102 and the second attachment 104, it is thus determined that the shrinkage degree of pyloric ostium or other body orifice.Such as when described technology is used to shrink the pyloric ostium 1102 as shown in Figure 11 B and Figure 11 C, the size (such as diameter or other size) of the confined pyloric ostium 1102 of definable lengths of Part I 108, this is smaller in size than the natural size of the pyloric ostium 1100 shown in Figure 11.The size of the pyloric ostium 1102 shown in Figure 11 B is restricted compared with the natural size of the pyloric ostium 1102 shown in Figure 11 A.The size of the pyloric ostium 1102 shown in Figure 11 C increases to some extent relative to the size of the pyloric ostium 1102 shown in Figure 11 B.
In some cases, after body orifice size is limited, it may be desirable to increase body orifice size or recover to its natural size.Such as, when hereinbefore technology is used to restriction pyloric ostium size to help patient's loss of weight and when therefore treatment is fat, pyloric ostium size initial reduction may result in some inconvenience of patient (such as vomiting, nauseating and/or other undesirably symptom).Again such as, pyloric ostium initial reduction can make patient's loss of weight and be likely to be no longer necessary to be maintained at opening initial reduction size.In arbitrary these or other situation any, it may be desirable to increase by the size in limit aperture.
No matter increasing subsequently by pyloric ostium 1102 size of above-mentioned technical limitations is what reason, pyloric ostium 1102 can by cutting off or the Part I 108 of otherwise disrumpent feelings connector 106 expands, as shown in Figure 11 C signal, wherein, Part I 108 is cut into two parts 108a and 108b.As a result, as shown in Figure 11 C, the spacing of implant 202,402 can increase to the second distance d depending on Part II 110 length2, Part II is time the longest part of connector 106, and it is also as shown in Figure 1B (not shown implant).If because any reason needs to increase pyloric ostium 1102 size, then the Part II 110 of connector 106 can be cut off and the spacing of the first attachment 102 and the second attachment 104 can increase further, for instance increases to distance d as shown in Fig. 1 C (not shown implant)3.It is undesirable that restriction pyloric ostium 1102 size, then the Part III 112 of connector 106 also can be cut off, thus makes pyloric ostium 1102 recover to its not limited natural size.
Therefore, described embodiment provides simple and adjustable reversible technique for controlling body orifice size.Implant 202,402 is configurable to the puncture orifice during effective closed group is knitted, and it allows to reduce the damage to organizing and lose blood.Connector 106 can be made up of this material, i.e. the end (end such as the part 108a produced because cutting off Part I 108 in Figure 11 C, 108b) of cut-off parts will not damage surrounding tissue.Therefore, body orifice size can control non-invasively.It is undesirable that all parts that the body orifice limit applies constraint and connector 106 are cut off, then implant 202,402 can stay in the body and allow puncturing tissue to heal.As another alternative, owing to nearside alar part and distally alar part are configured to reversibly deployable and can be compressed to mobile to unexpanded configuration, therefore implant 202,402 can be removed from surgical sites.
In certain embodiments, at least one part of connector 106, some parts or all parts and/or whole device 100 can be bioresorbables.Addedly or alternatively, one or more components of implant 202,402 can be bioresorbable.Therefore, after connector 106 is no longer used to restricted orifice size, implant 202,402 can stay surgical sites, until they are completely absorbed or partially absorb, this can extend a period of time being enough to make tissue cure.
